12KV HRC Current-limiting Fuse

The SARAH Electric's 12KV HRC Current-limiting Fuse is meticulously designed in accordance with international and domestic standards such as IEC and GB. It achieves rapid circuit breaker operation through the current-limiting principle, capable of limiting and cutting off the fault current before it reaches its peak value in the event of a short-circuit fault. This effectively prevents the impact of the fault current on equipment such as transformers, switch cabinets, and lines

Product Series and Core Technical Parameters

Product Series Classification

The SARAH high voltage current limiting fuse is divided into two main series, which are suitable for different application

XRNP Series: High-voltage current-limiting fuses for voltage transformer protection, featuring low current and high breaking capacity, suitable for short-circuit protection of voltage transformers and small-capacity equipment.

XRNT Series: High voltage current-limiting fuses for transformer protection, covering a wide current range, suitable for main circuit protection of distribution transformers, switch cabinets, and lines, etc.

Analysis of Core Performance Parameters

With a maximum current of 50kA and 12KV, the HRC Current-limiting Fuse can handle extreme short-circuit faults, quickly cutting off the faulty current and protecting the equipment from damage.

Suitable for a full temperature range of -40℃ to +60℃, resistant to ultraviolet rays, resistant to high humidity and heat, and resistant to salt fog. It is suitable for various outdoor and indoor scenarios.

The 12KV HRC Current-limiting Fuse is equipped with high-temperature-resistant and high-insulation ceramic/epoxy housing. Its withstand voltage under normal frequency and lightning impulse conforms to international standards.

Core Functions and Advantages of the Product

Core Protection Functions

1. When a short circuit fault occurs in the line or equipment, the fuse instantly melts, cutting off the faulty current within milliseconds, preventing the accident from escalating and avoiding the damage to transformers and switch cabinets.

2. When the load exceeds the rated current for a long time, the fuse gets overheated and melts, achieving overload protection and ensuring the long-term stable operation of the equipment.

3. After melting, a distinct electrical break occurs, meeting the safety isolation requirements for power maintenance and eliminating the need for an additional isolating switch.

4. Pure mechanical thermal effect action. The 12KV HRC Current-limiting Fuse does not rely on secondary power supply or control circuit. Even in extreme power failure situations, it can still provide normal protection.

Core Product Advantages

Covering all voltage levels from 3.6kV to 40.5kV, and all current ranges from 0.5A to 200A.
